Hi all,
I am facing slow data transfer in my LAN. In the LAN I have one Cisco 3850 L3 switch connected to Cisco 2960 L2 switch in another block through fiber link. When we transfer file from Server to PC I am getting about 1 MB/sec to 2 MB/sec and if we transfer file from PC to server then speed is 90 to 100 Mbps.
Solved! Go to Solution.

Yes, drops seem to be a problem. You need to align your hardware selection and either use single or multi-mode:
The selection is usually based on the availability of installed cable and the distance that you need to go.
Hope this helps,

can you do the file upload/download, as close to the server as you can an make the components in the path shorter.
because this is not necessarily a network problem. can you pump the file from one server to the other on the same host?

What is the transfer speed from a PC to PC (same switch) vs server to server (same switch)?
Wait ... server? Connected to a 3850?

Send us config of fibre link port and interface stats. See if its clocking up errors. Cheers

Hi Manish,
That is correct, but you will also have to change the SFPs to single-mode ones (1000BaseLX). The part code is GLC-LH-SM.
Hope this helps,
Dave

Hello
You may also consider using mode conditioning cabling, These can be used in certain circumstances between SM/MM fibre patching
